Can you provide the code used? or at least the polygons in a human readable format (the reader I tried could not read the file).

well you might want to double check my file, but I don't see any
degenerate segment in my polygons. But I thought about it, maybe it was
a problem at the junction between first and last points, so I skipped a
few points at the end when reading the file, and I still have this
problem. I must add that this configuration works fine when I use GEOS.

I didn't specified my system : Visual Studio 2010 on win XP, if it's of
any help.

without looking at the file, it is highly probable that you have a
segment made of two identical points.
